Speed Sensor
Magnetic Pickup type (13/16 NC thread) operating typically off the flywheel for pulse genera-
tion (frequency input to the ECU). It connects to the harness with a 2 pin Packard Weather-
pack connector. It must be mounted to the bell housing where it is in close proximity to the
engine flywheel teeth.
Pressure Transducer
The transducer is a 300 PSI gauge pressure sensor. The PSI sensor is a voltage generator
based on pressure with a range of 4 volts DC starting at 700 mV atmospheric pressure. It is
connected to the harness with a 3 pin Packard Metri-pack connector and provided with a 5
VDC source and signal ground by the ECU. It should be mounted on the discharge side of
the pump. At the rear of the Pressure Test Port or Master Discharge Gauge is a desirable
location. The transducer is a critical component of the system that is the only piece that
provides pump pressure information to the ECU.
